specification.

This invention relates to certain new and useful improvements in railroad crossing signals and particularly to the type of signal that isautomatically operated by the wheels of rolling stockpassing over trip devices for both sounding an alarm and waving-a flag. I

The primary object of the invention is-to provide a railroad crossing signal wherein a post or stand located adjacent a railroad crossover, supports-abell and afia g statt pivotally mounted-thereto at one end with operating means for the bell and-flag staff including trip devices arranged adjacent a track rail for sounding the bell and waving the flag.

lVith the above and otherobjeot's in'view that will become apparent during the course otthe followingdescription, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational View of a railroad track equipped with the crossing signal apparatus forming the subject matter of the present invention,

Figure 2 is a top plan view of the track and signal apparatus,

Figure 3 is an enlarged side elevational view of the track showing the trip devices for operating the signal mechanism,

Figure 4 is a fragmentary top plan View of the track and the signal apparatus associated therewith,

Figure 5 is a cross-sectional view taken on line VV of Fig. 4 showing the trip operated lever having link connections with a bell hammer and a flag stafi',

Figure 6 is an end elevational view showing the post adjacent the cross-over supporting the bell and flag and the operating means therefor,

Figure 7 is a detail sectional view taken on line VII-VII of Fig. 6,

Figure 8' is a si'd'e'el'evational View of the signal post,

Figure 9-is an enlargeddetail side elevationa'l viewof a portionof the track rail showing the-trip device at the end of a series, and

Figure 10 is adetail sectional=view taken Referring more in detail to'the accompjanying: drawings, there is'illustrated a railroad crossing signal, the railroad being represented by the ties1-supportingtrack rails '2 that traverse the cross-over 3 asshown in Figs dg The tie'l adjacent'the'cross- 7 include a plurality of 'trip devices arranged,

adjacent one ofthe rails 2"and' having operative connections with the bell and flagstaff, the trip devices being in the form of levers 9 pivotally mounted at 10 to the outer side of the rail 2, each trip lever 9 carrying an eyelet 11 adjacent the pivot point 10 and an eyelet 12 at its forward end and through which eyelets, a fiexible cable 13 freely extends. The cable 13 in passing through the end trip lever 9 positioned the greatest distance from the signal post 4 is directed downwardly as shown in detail in Fig. 9 and is anchored to the bracket 14 secured to the tie 1. The connection between the end cable 13 and bracket 14 includes a screw eye bolt 15 for tightening the cable and removing slack therefrom.

A bell crank lever 16 as shown in Fig. 4 is pivotally supported on the tie 1 outwardly of the rail 2 and has the adj acent end of the cable 13 attached to the leg 17 thereof. The other leg 18 has one end of a coil spring 19 attached thereto with the outer end of the spring anchored as at 20 to the tie 1 for normally holding the bell crank lever under tension with the cable 13 drawn to a taut condition.

As shown in Fig. 6, a bracket 21 suppoite upon the outer end of the tie l 'has a lever 22 pivotally mounted thereon as at 23, a link 24 being connected at one of its ends to the ofiset ortion of the lever 22 at the point 26 while the other end of said link is connected as at 27 to the outer end of the bell crank lever 18. The lever 22 has a link connection 28 intermediate the ends thereof with the flag stafi 7 and a link 29 connected at one end to the outer end'of the lever 22 is attached at its other end to the bell hammer 30 that is pivotally mounted as at 31 upon the post 4 adjacent the bell 5. In the normal position of the mechanism, the spring 19 holds the bell crank lever 18 under tension and the link connection 24 between the bell crank and lever 22 holds the lever 22 at its limit of downward movement with the flag staff 7 loweredand the bell hammer 30 ele vated at its striking end. When the wheels of rolling stock pass over the trip levers 9, the same are successively moved upon their pivot points 10 with the forward ends of the trip levers 9 lowering o-r pulling upon the cable 13 to shift the bell crank lever 18 and elevate the lever 22 for raising the flag staii 7 and causing the hammer 30 to strike the bell 5. The car wheels will successively operate the trip levers 9 and cause the flag to be waved and an intermittent striking or sounding'of the bell.

'VVhile there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope ,o-r the invention as claimed.

.VVhat is claimed as new is 1- 1. In a rallroad crosslng signal, a signal post, a bell on the post with a hammer adjacent the same, a flag stafi' pivoted on the post, means associated with the bell hammer and flag staff and operated by the wheels of rolling stock for ringing the bell and swinging the flag stafi, said means including a lever pivotally mounted at one end and having a link connection with the bell hammer at its outer free end and an intermediate link connection with the flag staff, a bell crank lever having a link connection with the aforesaid lever, a cable connected to the bell crank and extending along a track rail, and spaced wheel engaging trip devices for operating the cable.

2. In a railroad crossing signal, a signal post, a bell on the post with a hammer adjacent the same, a flag staff pivoted on the post, means associated with the bell hammer and flag staff and operated by the wheels of rolling stock for ringing the bell and swinging the flag stafi', said means including a lever pivotally mounted at one end and having a link connection with the bell hammer at its outer free end and an intermediate link connection with the flag stafi", an offset carried by the lever adjacent its pivot point, a bell crank lever having a link connection with the ofiset portion of the aforesaid lever, a cable connected to the bell crank and extending along a track rail, and trip levers associated with the cable and operated by the wheels of rolling stock.

In testimony whereof I affix my signature.
